Riser bolt conversion: metric to standard?

[ds06nomad]

It's taking forever to get the risers I ordered, and I'm about out of patience. So, I'm wondering if the Thunder Mfg. adapter bolt that allows metrics to use HD risers would be a remedy? I can then practically go buy a set of risers off the shelf and be done with this project.

Or, can I find the same set of bolts at a hardware store? At this point it's not even about the $20 for two lousy bolts, it's frustration, pain, and the dead hand syndrome talking...

Thanks for any input, especially from those who have converted the stock risers to standard threading.

Best,
